20090326276 | METHOD FOR THE PRODUCTION OF CYCLIC KETONES - The present invention relates to a process for preparing a cyclic ketone having from 7 to 16 carbon atoms, which comprises at least the steps | 12-31-2009 |
20110288341 | Process For Producing Cyclohexylbenzene - In a process for producing cyclohexylbenzene, benzene and hydrogen are fed to at least one reaction zone comprising a catalyst system which comprises a molecular sieve and at least one hydrogenation metal. The MCM-22 family molecular sieve having an X-ray diffraction pattern including d-spacing maxima at 12.4±0.25, 6.9±0.15, 3.57±0.07 and 3.42±0.07 Angstrom, and the hydrogenation metal is selected from the group consisting of palladium, ruthenium, nickel, zinc, tin, cobalt, and combinations of any two or more thereof Hydroalkylation conditions of temperature and pressure are selected to produce a hydroalkylation conversion in a range of from about 15% to about 75% The benzene and hydrogen are then contacted in the at least one reaction zone under said selected hydroalkylation condition to produce an effluent containing cyclohexylbenzene. | 11-24-2011 |
20120157719 | TUBE BUNDLE REACTOR FOR UNCATALYZED OR HOMOGENEOUSLY CATALYZED REACTIONS - The invention relates to a tube bundle reactor with a flat feed hood. Alternatively, the release hood may also have a flat design. The flat design reduces the heat of reaction which arises in the hood in the case of reaction types which take place not only in the tube bundle (uncatalyzed reactions and reactions with homogeneously distributed catalyst). This greatly suppresses undesired reactions which already take place in the hood owing to accumulated heat, which achieves a higher selectivity in the case of thermally sensitive reactions. In addition, the thermal distribution within the hoods can be controlled precisely. | 06-21-2012 |
20140323767 | PROCESS FOR THE PRODUCTION OF 1,3,3-TRIMETHYL-2-(3-METHYLPENT-2-EN-4-YNYL)CYCLOHEX-1-ENE - The present invention relates to an improved process for the production of 1,3,3-trimethyl-2-(3-methylpent-2-en-4-ynyl)cyclohex-1-ene, highly enriched in the Z-isomer, and the use of such compounds in organic syntheses, especially in processes forming intermediates (building blocks) the synthesis of vitamin A or β-carotene or other carotenoids, e.g. canthaxanthin, astaxanthin or zeaxanthin. | 10-30-2014 |
20150094495 | Process for Producing Phenol and Cyclohexanone - In a process for separating a mixture comprising cyclohexanone and phenol, at least a portion of the mixture is distilled in the presence of a solvent including at least two alcoholic hydroxyl groups attached to non-adjacent saturated carbon atoms, water, and in the presence or absence of a hemiketal defined by the formula (I) or the formula (II): | 04-02-2015 |

20140031592 | METHODS OF CONVERTING MIXTURES OF PALMITOLEIC AND OLEIC ACID ESTERS TO HIGH VALUE PRODUCTS - The invention describes methods and systems for making particular organic compounds from unsaturated fatty acids derived from biological materials. Particular embodiments describe synthesizing civetone and olefins from a mixture of palmitoleic and oleic unsaturated fatty acid esters. The inventive methods use reaction steps such as metathesis, cyclization, hydrolysis, and/or decarboxylation. | 01-30-2014 |
20140316166 | Production of Cyclohexylbenzene Hydroperoxide - In a process for producing cyclohexylbenzene hydroperoxide, cyclohexylbenzene is contacted with oxygen to produce a reaction product comprising cyclohexylbenzene hydroperoxide and unreacted cyclohexylbenzene. The reaction product is then maintained under conditions such that crystals of cyclohexylbenzene hydroperoxide form and separate from the reaction product. The cyclohexylbenzene hydroperoxide crystals are then recovered from the reaction product. | 10-23-2014 |
20100137646 | PROCESS FOR THE PREPARATION OF XANTHOPHYLL CRYSTALS - The invention describes the preparation and isolation of xanthophylls from plant sources. whereby a transesterification process is utilized without the necessity of an aqueous format. | 06-03-2010 |

20100081848 | METHOD FOR PRODUCING OXIDATION PRODUCT OF CYCLOALKANE - Disclosed is a method for industrially efficiently producing a corresponding useful oxidation product such as a cycloalkyl hydroperoxide, a cycloalkanol, and/or a cycloalkanone, especially a particularly useful cycloalkanone, from a cycloalkane with a high selectivity in a good yield at low cost. This method is advantageous in respect of energy and process. Specifically, an oxidation product of a cycloalkane is obtained by oxidizing the cycloalkane in a liquid-liquid two phase system using an aqueous solvent in the presence of a nitrogen atom-containing cyclic compound which contains, as its ring constituent, a structure represented by following Formula (I): | 04-01-2010 |
20110034735 | METHOD FOR PRODUCING CATECHOL - Provided is a method for producing catechol in a one-pot by reacting (4S,5R,6S)-4,5,6-trihydroxy-2-cyclohexene-1-one under hydrogen-reducing conditions while heating. | 02-10-2011 |
20110160489 | Process for Producing Phenol and Methyl Ethyl Ketone - In a process for reducing the level of tert-butylbenzene in a mixed butylbenzene feed comprising tert-butylbenzene and sec-butylbenzene, the feed is contacted under dealkylation conditions with a catalyst system comprising a dealkylation catalyst whereby the tert-butylbenzene is selectively dealkylated to produce an effluent stream which comprises benzene and which has a lower concentration of tert-butylbenzene than said feed. | 06-30-2011 |
